 Within a fortnight of Deans' return from the south, the Surveyor-General to the New Zealand Company, Captain W. Mein Smith, left Wellington to examine the harbours on the east side of the South Island.Deans' tour had been a private investigation; Captain Smith's was an official survey.Unfortunately, after completing the southern part of his work, covering the coast between Akaroa and Stewart Island/Rakiura, Captain Smith lost his charts, field books, and surveying instruments in the wreck of the cutter "Brothers" inside Akaroa heads on 10 November 1842.
